iOS之UIImagePickerController的应用

直接代码敬之

@import MobileCoreServices;

@import AVFoundation;

<UIImagePickerControllerDelegate,UINavigationControllerDelegate>

 

get方法

- (UIImagePickerController*)imagePicker{

    if (!_imagePicker) {

    _imagePicker = [[UIImagePickerController alloc]init];

    //_imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

    _imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;

    _imagePicker.cameraDevice = UIImagePickerControllerCameraDeviceRear;//摄像头分前后

        

        _imagePicker.allowsEditing= NO;

        //_imagePicker.allowsImageEditing = YES;

        

        UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];

        [button setBackgroundColor:[UIColor yellowColor]];

        [button setFrame:CGRectMake(80, 580, 50, 50)];

        button.layer.cornerRadius = 25.0;

        [_imagePicker.cameraOverlayView addSubview:button];

        

        _imagePicker.showsCameraControls = NO;

       // _imagePicker.cameraViewTransform = CGAffineTransformMakeRotation(M_PI_2);

        _imagePicker.delegate = self;

    }

    

    return _imagePicker;

}

 

事件响应实现跳转：注意貌似不能在viewdidload中操作

 [self presentViewController:self.imagePicker animated:YES completion:nil];

 

#pragma   - mark    UIImagePickerControllerDelegate

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo {

    NSLog(@"%s",__func__);

 

}

    }else{
